speciate: Speciation of emissions

Description

speciate separates emissions in different compounds. It covers black carbon and organic matter from particulate matter. Soon it will be added more speciations

Usage

speciate(
  x = 1,
  spec = "bcom",
  veh,
  fuel,
  eu,
  list = FALSE,
  pmpar,
  verbose = FALSE
)

Value

dataframe of speciation in grams or mols

Arguments

x

Emissions estimation

spec

The speciations are:

• "bcom": Splits PM2.5 in black carbon and organic matter.

• "tyre" or "tire": Splits PM in PM10, PM2.5, PM1 and PM0.1.

• "brake": Splits PM in PM10, PM2.5, PM1 and PM0.1.

• "road": Splits PM in PM10 and PM2.5.

• "nox": Splits NOx in NO and NO2.

• "nmhc": Splits NMHC in compounds, see ef_ldv_speed.

• "pmiag", "pmneu", "pmneu2": Splits PM in groups, see note below.

veh

Type of vehicle:

• "bcom": veh can be "PC", "LCV", HDV" or "Motorcycle".

• "tyre" or "tire": not necessary.

• "brake": not necessary.

• "road": not necessary.

• "nox": veh can be "PC", "LCV", HDV" or "Motorcycle".

• "nmhc"see below

• ""pmiag", "pmneu", "pmneu2": not necessary.

fuel

Fuel.

• "bcom": "G" or "D".

• "tyre" or "tire": not necessary.

• "brake": not necessary.

• "road": not necessary.

• "nox": "G", "D", "LPG", "E85" or "CNG".

• "nmhc"see below

• "pmiag", "pmneu", "pmneu2": not necessary.

eu

Emission standard

• "bcom": "G" or "D".

• "tyre" or "tire": not necessary.

• "brake": not necessary.

• "road": not necessary.

• "nox": "G", "D", "LPG", "E85" or "CNG".

• "nmhc"see below

• "pmiag", "pmneu", "pmneu2": not necessary.

list

when TRUE returns a list with number of elements of the list as the number species of pollutants

pmpar

Numeric vector for PM speciation eg: c(e_so4i = 0.0077, e_so4j = 0.0623, e_no3i = 0.00247, e_no3j = 0.01053, e_pm25i = 0.1, e_pm25j = 0.3, e_orgi = 0.0304, e_orgj = 0.1296, e_eci = 0.056, e_ecj = 0.024, h2o = 0.277) These are default values. however, when this argument is present, new values are used.

verbose

Logical to show more information
